- RINsE WRINGER;

Albert Schellenberg, Joliet, Ill.` Application May 15,1941, SerialrNo.393,521,` ,v

This invention relates tofwringers of the type used in connection withmotor driven domestic washing machines, and particularly to that type ofwringer wherein a rinsing operation is performed. This application is animprovement on the rinse wringer set forth in my co-pending application,No. 368,159, filed December 2, 1940, now Patent No. 2,358,256, grantedSeptember 12, 1944.

The particular object of the present invention is to provide improvedconveyor and rinsing means in the rinse chamber of the wringer.

Other objects and benefits will be disclosed in the followingdescriptions and drawing, in which Fig. l is a cross-sectional elevationview of a rinse wringer having a conveyor belt over the rolls and spraymeans to agitate and rinse the garments passing between the two sets ofrolls.

Fig. 2 is a similar cross-sectional view showing a wringer having aconveyor between the two sets of rolls with spray means to agitate andrinse the garments as they are carried through the rinsing chamber.

Fig. 3 is still another similar cross-sectional View showing a wringerhaving a conveyor between two sets of rolls with an eccentric acting onthe conveyor to agitate and rinse the garments, as will later beexplained.

It will be understood that all wringers, shown somewhat diagrammaticallyin the foregoing drawing, employ the reversible gear head driving therolls and conveyor, the safety pressure release for the upper frame, theclutch to stop operation of the rolls and conveyor when pressure isreleased, the rinse basin overflow, and generally all necessarymechanical structure shown in the aforesaid application, Serial No.368,159, together with any necessary modifications of this structure ascould be accomplished by skillful mechanics experienced in the art. Itwill be appreciated that the present application deals with detailedmodifications of structure with the basic mechanism of the wringerremaining practically the same as shown in the aforesaid application,Serial No. 368,159.

Now referring to the drawing, I designate the lower frames by thenumeral l and the upper frames by the numeral Il. A conventional cam barfor release of the upper frames is shown as l Ir. This form of cam baris clearly shown in Fig. 4 as numeral lacoacting with latch members 20and 2l in my aforementioned application, Serial No. 368,159, now issuedas Patent No. 2,358,256 on September 12J 1944, and is completelydescribed therein. The dual pairs of 2v f drivingrolls are designated4IIL-l5 and lli-Il.l

The water level in the rinse 4ehangrber in each`v case is designated bythe letter L.

Now referring to Fig. 1, I show a wringer havperforated by holes I8 topermit rinse water to be drained readily through the belt. In some casesI may desire to, have rubber fingers I9 on theA belt, which lingerswillbe proportioned and arranged to lift clothes as they come throughthe rolls, thus agitating and holding them upward on the belt to permitthe rinse water from the spray tubes Sl, S2 and S3 to effectively rinsethe clothes thereon. It will -be noted that the spray streams from therinse tubes SI and S2 are directed forwardly at an angle, whicharrangement is desirable to agitate the clothes by resistance as theymove toward the right on the belt and thus effect better rinsing. Thesprays from nozzle spray tube S3 are directed vertically so that theymay pass thru the perforations 18" and be directed on the bottom of thegarments.

Now referring to Fig. 2, the conveyor belt is mounted on rolls 20--2Idriven from the power gear head as explained in the previous patentreferred to. The belt 22 has perforations 22 and rubber lingers 23 formore effectively rinsing garments, as explained above. Similarly, thespray tubes Sil-S2 have nozzle openings directing sprays angularlyforward to more effectively agitate and rinse the garments by resistingmovee ment of the clothes.

Now referring to Fig. 3, the conveyor belt is again mounted between thedual pairs of rolls on the rolls 3-3l and the eccentric roller 32, alldriven simultaneously from the power gear head. The resilient belt 33has perforations 33 and may be equipped with the rubber ngers 34 forthesame purpose as explained for Figs. 1 and 2. The nozzle openings in thetubes S4 are directed toward the rolls I-Il as the garments pass out ofthe wringer to afford rinsing of the cleaned rinse water just before theclothes are n finally wrung. It is not necessary in this case to use thespray to effect agitation because such agitation is effectively providedby the eccentric roller 32, which will effectively flap the belt 33 andthe clothes up and down slightlybelow the water level L to agitate anddouse the clothes by the movement from the eccentric roller 32.

Having thus described my invention, I claim:

1. In a rinse wringer, a rinsing chamber, a pair of intake rolls at oneend of the rinsing chamber, a pair of discharge rolls at the oppositeend of 3. In a rinse wringer, a rinsing chamber, an endless conveyorbelt mounted in said rinsing'-V chamber for moving Vgarmentstherethrough; saidl belt being of non-rigid materialand having .the Ywith, said belt having the periphery of opposite end portions thereofarranged in pressure relation with the squeeze rolls, the exible fingersyielding at the points of engagement therebetween. v

5. In a rinse wringer, a lower frame having a rinsing chamber extendingacross the frame, an upper frame covering and locked over the lowerframe by instantaneous release mechanism, coacting pressure rollsmounted on the inlet sides of the frames, coacting pressure rollsmounted on the outlet sides of the frames, and an endless 'conveyor belthaving projecting resilient fingers extending across the rinse chamberbetween the rolls t'o liftV and conveygarments through the s rinsechamber.
